Standard locks that are installed on interior doors are often replaced for various reasons. In addition, the finished canvas can be sold without a locking mechanism. Installing a door lock is a rather difficult operation, which requires an understanding of the device design and knowledge of the nuances of operation. The main factor determining installation features is a kind of locking mechanism.
Installing a lock on the door: choosing the type of locking mechanism
Design features are the main factor by which all locking devices used in interior canvases are classified. Consider the most popular devices installed in interior doors.
Latch (normal). This type of locking device is most common. Conventional latches are used in interior canvases everywhere. Installing the lock on the interior door in this case is not difficult, which often attracts buyers. The peculiarity of this device is that its design includes a cylinder and a locking tongue, controlled by a special mechanism. Most often, these locks are implemented complete with a handle. Thus, in order to avoid mistakes in the process of installation, it is necessary to study the instruction, which will allow to answer the question of how to insert a handle into the interior door.
Latch with retainer. The mechanisms that belong to this group are an improved modification of the previous variety of locking devices. In their design there is another element – the latch. Its function is to hold the lock in the closed state. For interior doors such products are the best fit.
Useful information! Today you can find two types of latches equipped with a lock: push-button and lever. For home use, it is recommended to pay attention to the second option.
Mortise mechanism. It is the second most popular interior door lock. Installation in the canvas requires precision and care. Mortise devices are reliable and have a long service life. They are most often used for doors in private offices and bedrooms. Unlike the previous type, these devices are opened by means of a key.
There are two types of mortise mechanisms. The first option provides for the possibility of unlocking the door on both sides (key-key). In the second case, a combination is used, which consists of a key and a pinwheel. In this situation, a separate inset handle in the interior door is required. How to perform this operation? For this there is a special step by step instructions.
Overhead lock. In terms of installation, this option is the most acceptable. However, overhead devices do not meet current safety standards. They can be easily destroyed by mechanical action.
Magnetic lock. The cost of such devices is higher than the price of standard types of locking mechanisms. Their main advantage is noiseless operation. That is why they are often mounted on interior doors that are intended for bedrooms and children’s rooms. Independently quite difficult to embed the lock in the interior door. The price of installation of magnetic mechanisms depends on the characteristics of their design and the type of door.
Lever device. Such devices are able to provide good protection of the room. They are opened with a key and are used not only for interior but also for entrance canvases.
Most often interior doors are equipped with locks, which are most suitable for operation in such conditions. These include flat and round mechanisms, which differ from each other in the shape of the body.
Flat interior locking devices are expensive. Their self-installation is accompanied by certain difficulties due to the design. However, such devices have one serious advantage: they provide a high degree of protection against the entry of unauthorized persons.
It is worth noting one important feature of flat mechanisms: their installation weakens the door and box. Before you insert a lock into a wooden door, you must install its compatibility with the canvas. Experts recommend installing flat products in cash doors. The cloths made of MDF are not suitable for installation of full-fledged flat mechanisms. In them, as a rule, cut short versions of devices.
Useful information! When mounting a flat mechanism on a door made of MDF, it is necessary to take into account that the reeds should not be more than 15 mm thick. And also in this case, the restriction extends to the end plate of the locking device. Its width must not exceed 24 mm.
Round locking mechanisms are the best option for installation in the home. Therefore, they are most often found in interior doors. It is not necessary to have special skills and abilities to install the lock in a wooden door. The main advantage of such devices is compatibility with canvases of any type. Most often, two types of handles are used for such mechanisms: falev and knobs. The second type of products is considered the most appropriate. Handles-knob recommended for installation in the home, as they are reliable and convenient.
In order to independently carry out the installation of the locking mechanism, it is necessary to prepare the appropriate tools. Installation of such devices does not require a large number of devices and accessories. The minimum set includes the following elements:
- pencil (for marking);
- measuring tape;
- drill;
- screwdriver;
- construction knife;
- chisels (10 and 20 mm);
- set of drills;
- masking tape
Before installation, it is recommended to study step-by-step instructions that will help you figure out how to install the lock on the interior door. It is worth noting that at the present time there are special kits on sale that can be used to insert locking mechanisms into webs made of various materials.
Sets for tapping locking devices, as a rule, include a perforated drill, the cross-section indicator of which is 22 mm. This part is not suitable for organizing the hole under the latch. In this case, it is recommended to use a chisel.
The end result of self-assembly of the locking mechanism depends on many factors. First of all, the degree of complexity of the installation is influenced by the type of door and the design of the lock itself. Experts advise to make a preliminary drawing of the device. It should contain information about the location of the future holes required for the locking elements, handles, etc.
Note! If the old mechanism is replaced with a new one, then it is recommended to study the instruction, which will allow you to understand how to disassemble the interior door lock with a handle.
The more detailed the drawing was drawn up, the less the likelihood of making certain mounting errors. Before installation, it is necessary to prepare the door for installation. The preparatory stage includes the layout of the canvas. This method will allow the lock to be correctly inserted into the interior door.
The first step is to determine the height of the castle above the floor. The standard value on which the locking mechanisms of interior canvases are located is 1 m. If desired, you can decrease or increase the distance from the floor by 10 cm. The final cost depends on the type of lock and the nature of the work. Repair of locking mechanisms can cost approximately 1500 rubles.
After determining the desired height of the device, it is necessary to glue the place in which the installation will be carried out with masking tape. Most often, a complete template is sold with closure mechanisms, which allows you to perform accurate marking for a specific model. It must be attached to the butt and flat surface of the door.
Mark all the necessary points at which the holes will be made to install fasteners, it is possible without the use of a template. For this there is an instruction that you need to pay attention. The markup is made with a pencil or chalk.
First of all, it is required to measure a distance of 1 m from the floor. A horizontal mark is made at the desired point. Next, you need to hold a vertical line. The point of intersection of the two lines is the mounting center of the locking mechanism. The preparatory stage of the tie-in of the castle into the interior door with their own hands requires special care. After marking the place in which the locking device will be located, the points corresponding to the latch holes (on the front surface) and the door handle are determined.
Then you need to attach the case of the locking mechanism to the lines and mark the bottom edge of the device. Next, you need to dissolve the slats. The distance in this case corresponds to the thickness of the lock. After the wiring, the marking of two parallel lines is carried out, which should be perpendicular to the horizontal straight lines at a distance of 5 cm.
Note! The accuracy of the measurements affects the correct installation of the lock and handle in the interior door. Marking errors lead to various malfunctions that prevent the normal operation of the locking device. The lock is installed on the front side of the door leaf. At the same time, it is necessary to clearly outline the center point.
Next, you need to mark up the positions in which the latch and handle will be located. After that, the mating hole located on the door frame is marked.
The next stage, which follows the marking of the door leaf, involves making holes for the handle and locking mechanism. This process is also divided into several stages.
First, you need to prepare a tool that will be used to organize the holes. The easiest way to do this work is with a screwdriver and a special nozzle (wood crowns). The opening for the mechanism of the locking device is made on the flat surface of the door leaf. And first you should make a recess on the outside, and then on the inside. This procedure will avoid damage to the electronic screwdriver.
The crown is used to organize the holes for the core and the handle. Installation on the door of the locking mechanism is made using another nozzle – a pen drill. It is used to make a latch hole on the front side of the web. It is important to remember that the drill must be immersed in wood at a right angle.
Then you need to remove the tool and use the construction knife to remove the outer layer of wood in accordance with the marked lines. After that, through the chisel you need to organize a groove for the bolt. Its depth should not exceed the width of the crossbar frame. At the end, the latch is installed and fixed with self-tapping screws.
The easiest way to install the locking mechanism involves the use of a milling device. Milling cutter is a vertical machine, which has small dimensions and is quite easy to use. In order to install the lock into the interior fabric using a milling device, you must first remove the door from the hinges and put it perpendicular to the floor (side).
Next, you need to perform measurements and set tags corresponding to the location of the tongue mechanism. The next step in installing your own lock in the interior door is to transfer the device parameters to the canvas. To do this, you need to put a lock on the surface of the door and circle his body with a pencil.
Note! In order to exclude the possibility of making mistakes, it is recommended to study the video materials that will help to answer the question of how to insert the lock into the interior door. Video and photos allow you to study in more detail all the nuances of the process.
Then on the side of the canvas you need to bring a straight line. After that, using the machine you need to perform a recess for the lock. The next step involves changing the nozzle on the milling machine and making the nest for the lock body. The exact implementation of this manual helps to correctly organize the opening for the locking mechanism. To check the correct operation, you need to check the device with the place prepared for it.
Both parts of the handle have special screw holes. These elements are applied to the outer and inner side of the door and fixed together. Next, you need to install a decorative ring, after which the handle must be pressed before the appearance of a characteristic click, which signals the end of the installation.
Thus, the installation of the handle on the interior canvas is not a very difficult event. It is required to remember that the installation process is influenced by factors such as the door material, type of lock, kind of handles. If necessary, you can always use the services of a qualified specialist, who will install the installation correctly and as soon as possible.
